I get the error by validating that there was no endpoint listening on "myservername"/server.svc. Maybe caused by incorrect addrees of Soap action.

It says see innerexception ( what I cannot find)

I did install the client as described in the manual, the same on my I-Pad.

What is the reason and what do I have to do. It is my first install of Pulseway

Try opening https://myservername/server.svc in a web browser from that computer, what is the result?
